To all whom it may concern:

Be it known that we, WILLIAM E. TONNER and WILLIAM B. LINDSAY, ofSteubenville, in the county of Jefferson and State of Ohio, haveinvented an Improvement in Filters and Cleaners, of which the followingis a specification.

This invention relates generally to filters, and particularly to thatclass thereof known as porous-wall filters, in which the water is forcedthrough the walls of a porous cylinder or receptacle.

More particularly stated, the invention is a device for cleaning theexterior of such receptacle and is an improvement upon the device shown,described, and claimed in our applications filed May 14, 1895, SerialNo. 549,310, and June 10, 1895, Serial No. 552,237.

This application is also a division of the application filed October 28,1895, Serial No. 567,143.

This invention consists in the peculiar construction of the severalparts and the novel manner of combining or arranging the said parts, allof which will be fully described hereinafter and pointed out in theclaims.

In the drawings forming a part of this specification, Figure 1 is a sideView of our filter, partly broken away. Fig. 2 is a verticallongitudinal section. Fig. 3 is a horizontal section on line 3 3 of Fig.2. Figs. 4 and 5 show details of construction. Fig. 6 is a verticaltransverse section on line 6 6 of Fig. 1.

In carrying out our invention we employ an outer case A, having a bottoma, on which is produced a socketed boss a.

The filtering-cylinder 13 is of porous 1naterial and has adischarge-pipe 0 extending thereinto, said pipe being closed at thebottom by means of a nut c, which has a lug c, adapted to fit in thesocketed boss at, and thus act as a pivot for the filtering-cylinderwhen it is desired to revolve the same. The porous filteringcylinder isarranged eccentrically within the outer case and nearer the front sidethan the rear, the purpose of which is to allow more space 'for theintroduction of a cleaner or scraper D, which is preferably co1nposed ofnatural stone of the character described in our Patent No. 528,104,granted October 23, 1894. This scraper D has a piston E centrallymounted upon the rear side, which piston projects through the opening 8in the outer case and into the Water-supply pipe F, which is preferablyconstructed with a globeshaped chamber f, into which the rear end of thepiston extends. This piston is made hollow and may be left open orpartially closed at the rear end, and near the forward end is providedwith an upwardly-opening aperture G, from which the water issues intothe outer case and around the exterior of the filteringcylinder.

The piston is made fiat on one side, as shown at e,and the end of thesupply-pipe is similarly shaped, sothat when said piston is set in avertical position it cannot turn or become misplaced. The water passesthrough the supply-pipe and piston out through hole G, and in doing sothe cleanerof stone is pressed against the side of thefiltering-cylinder. The cylinder being eccentric to the case and havinga discharge-tube projecting through the top, said tube is made in twoparts-nainely,-

the cap-piece h, through which the pipe projects, and the clamping-ringh, which binds the cap-piece to the top of outer case, and a suitablepacking-ring I being interposed to prevent leakage, and a stuffing-box Ksurrounds the discharge-pipe, which is preferably constructed with adetachable curved end and a regulating-cock, whereby the discharge offiltered water can be regulated.

The discharge-faucet L is located at one side of outer case near thebottom and is used when cleaning the filter, as presently described. I

In operation the water is admitted through the coupling and passesthrough the supply pipe and tubular piston into the outer case orreceptacle, entirely surrounding the filtering-cylinder. The waterentirely incloses the exterior surface of the filtering-cylinder, andthus renders the filtering operation quicker and easier.

when it is desired to clean the exterior surface of thefiltering-cylinder, the dischargefaucet is opened and the cylinderrevolved by simply turning the discharge-pipe, and as the water isaround the entire exterior surface the cleaning operation can beaccomplished very quickly and easily, and an abu 11- dance of hydraulicpressure will always be had through the medium of the tubular piston.

While we have mentioned a natural-stone cleaner as best adapted forcleaning the filtering-cylinder, it is obvious that a metallic cleanercan be employed without departing from the spirit of our invention.

e desire it to be understood that we do not broadly claim herein theeccentric arrangement of the filteringeylinder in order to provide roomfor a cleaner, nor the eccentric top and clamping-ring, such beingclaimed in our application, Serial No. 567,143, filed October 28, 1895,and hereinbefore referred to.

Having thus fully described our invention, What we claim as new, anddesire to secure by Letters Patent of the United States, is

1. In a filter of the class described the combination with the outercase and the inner filtering-cylinder, the cleaner and the supplypipe,of the tubular piston attached to the cleaner,havin g alongitudinalbore, and an upwardlydischarging aperture communicating with said bore,said piston having a flattened side, substantially as and for thepurpose set forth.

2. In a filter of the class described, the combination with the outercase and the innerfiltering-cylinder, of a natural-stone scraperarranged between said outer case and inner filtering-cylinder, a tubularpiston attached to said scraper and having a flattened lower side, thewater-supply pipe, the dischargepipe, and the discharge-faucet, allarranged substantially as shown and described.

In a filter, the combination with the outer cylinder, of afiltering-cylinder situated therein, an eccentric top to said filter,the discharge-pipe and draw-otf cook, the inlet arranged about midwaythe height of the cylinder, a piston movable in said inlet-pipe, acleaner rigidly fixed to the inner end of said piston, said piston beingtubularin form and closed at the inner end and having an opening in theupper side causing the stream to project upward toward the top of thecylinder, the inner cylinder being revoluble, and the cleaner beingfixed, substantially as shown and described.
